Compact, low cost connector system for flexible tubing is adapted to removably connect a length of flexible plastic tubing for rotational but not axial movement to a recessed opening in a body member such as a pneumatic valve, a fitting, or an air cylinder. A generally cylindrical, hollow plastic sleeve member surrounds the tubing, and is firmly anchored to it by a U-shaped metal retaining clip which is slidably movable in, and retained by, a pair of facing slots located near the outer end of the sleeve member. The slots are located in each of two legs of the sleeve which are spaced from each other except at the sleeve's inner end where they are joined. The sleeve member is assembled to the recessed opening by squeezing its legs together to allow opposed projecting tabs on each of the legs to enter the opening. The legs are then released so the tabs can snap into, and be retained by, a radially extending recess means in the wall of the opening. The tubing is then pushed into the sleeve member, past an O-ring mounted at the inner end of the recessed opening, and into a smaller diameter recessed opening. The tubing is then locked to the sleeve member by pressing the retaining clip into the sleeve's slots. The legs of the clip slightly compress and deform the tubing and have sharp edge portions which slightly cut into it to prevent it from being removed by pulling or by fluid pressure, yet permitting rotation of the tubing relative to the body member.
